Abstract
The invention discloses an anti-floating method and structure for LPM (lumped plasticity model) hollow die construction. The specific construction method of the anti-floating method for the LPM hollow die construction comprises two steps as follows: fixing bottom rebars on a floor template and fixing a hollow die on the bottom rebars, wherein the bottom rebar fixing method comprises the steps as follows: holed anti-floating steel strips are pressed at joint positions of vertical and horizontal bottom rebars, long screws are penetrated into holes of the holed anti-floating steel strips and screwed into the floor template by an electric hand drill, so that the bottom rebars are fixed on the floor template; and the hollow die fixing method comprises the steps as follows: at least two steel wires penetrate through the bottom rebars and bind the LPM hollow die, and concrete cushion blocks are laid between the LPM hollow die and the bottom rebars, and the LPM hollow die is fixed on the bottom rebars. The anti-floating method and structure are simple in manufacture technology, convenient and flexible in construction, low in manufacture cost and broad in engineering application prospect, can increase the construction speed and shorten the construction period, can effectively guarantee the floor construction quality, and can be popularized and applied in LPM hollow die construction.
Description
Technology explanation
The present invention relates to a kind of LPM hollow mold construction anti-float method and structure, originally belong to technical field of building construction.
Background technology
LPM hollow building cover is cast-in-place concrete hollow building roof version newly developed in recent years, with traditional beam and slab type building
Lid is compared, LPM hollow floor structure from heavy and light, span is big, shock resistance is strong, sound insulation, good heat-insulation effect the features such as.This kind of building
Lid, floor clear height increases, and can make full use of space, reduces floor design height, facilitates all kinds of distribution of pipe, significantly
Reduce reinforcing bar, concrete material consumption, thus reducing comprehensive cost.
LPM hollow mold from heavy and light, easily because concreting method is improper or fixing meanss are not in place in work progress
Float etc. factor, lead to floor that the mass defects such as cavity, leakage muscle occur, therefore, the anti-floating Resolving probiems of LPM hollow building cover are
The key that LPM hollow building cover is widely popularized.Conventional anti-float method is to use iron wire and thumb screw after the completion of hollow mold is put
It is directly anchored in template, the method constructing operation speed is slow, anti-floating effect is undesirable, and form removal inconvenience easily makes floor template
Face is damaged.
Content of the invention
Anti-float method and structure it is an object of the invention to provide a kind of LPM hollow mold is constructed, its processing technology is simple, applies
Work is convenient, flexible, and low cost of manufacture can accelerate speed of application, the reduction of erection time, to overcome the deficiencies in the prior art.
Present invention
A kind of LPM hollow mold construction anti-float method, this LPM hollow mold construction anti-float method is floor template, pacifies in length and breadth
The bottom reinforcing bar of dress and LPM hollow mold interfix for one integrally, and its concrete construction method includes bottom reinforcing bar and is fixed on floor template
Upper and hollow mold is fixed on two parts on the reinforcing bar of bottom, and wherein bottom reinforcing bar fixing meanss are vertical using anti-floating steel band with holes in gland
At the reinforcing bar knot point of horizontal bottom, then long spiro nail is penetrated by the hole of anti-floating steel band with holes using electric hand drill and hammers in floor template, real
Existing bottom reinforcing bar is fixed on floor template, and hollow mold fixing meanss are to pass through bottom reinforcing bar using at least twice steel wire and tie up
LPM hollow mold, and it is covered with concrete pad in the middle of LPM hollow mold and bottom reinforcing bar, thus realizing LPM hollow mold to be fixed on bottom steel
On muscle.
In the float Structure that above-mentioned LPM hollow mold is constructed constructed by anti-float method, described float Structure includes will by drawing
Seek mounted floor template, the bottom reinforcing bar intersecting in length and breadth is equipped with floor template, be provided with the with holes anti-of through hole at two ends
Floating steel band gland is at the interface point of bottom reinforcing bar, and is fixed in floor template through through hole by long spiro nail, on the reinforcing bar of bottom
It is sequentially placed mixed mud cushion block and LPM hollow mold, then bottom reinforcing bar is passed through using at least twice steel wire and ties up LPM hollow mold.
In above-mentioned float Structure, it is convex structure in the middle part of described anti-floating steel band with holes.
In above-mentioned float Structure, described steel wire is the annealing processing through techniques such as cold-drawn, heating, constant temperature, insulations
Black wire, and a diameter of 1mm～5mm.
Due to employing technique scheme, compared with prior art, the fixing bottom muscle special steel strip intensity in the present invention
Height, and fixed using long spiro nail, using the build-in force of slab form and screw, fixed form is reliable, and long spiro nail for maximum limitation
Do not need to complete to penetrate slab form, the assembly and disassembly of aspect anti-floating with holes steel band, and slab form will not be destroyed, fixing core steel wire
Using special process molding, more soft compared with ordinary steel wire, faster, space is less, and core is no damaged, and effect is non-for binding speed
Chang Mingxian, additionally, steel wire end is pricked, foot probability is lower, and reduction gluten colligation security risk, by being located at LPM hollow mold and bottom
Mixed mud cushion block in the middle of reinforcing bar, can more LPM hollow mold fixed effect more preferably, being proved the method in actual applications can have
Effect ground solves LPM hollow mold On The Floating in concreting process, and it is ensured that floor slab construction quality, future in engineering applications is wide,
Can promote the use of in the construction of LPM hollow mold.
